This apparently has been fixed since 2016.  I tested using the development branch on 8/15/18.  Closing report.

The attached patch causes several problems.  Retagging as "In progress" from "Patch submitted".

Here is a draft patch change to allow "clear all" not to remove breakpoints.

When the GUI is active, the focus seems to alternate between the edit window and the command window for a short period after clearing a function.  I'm not sure the best way to fix that.  Perhaps there should be a general mechanism for opening an edit window without giving it focus, and that should be used by the debug related functions.

(file #36448)

The behaviour has changed since 4.0.0, especially with changeset 0a09c3cae800, but this script is still problematic.

Now, the "clear all" clears the breakpoints but does not update the GUI's markers for them, and they cannot be removed by clicking on the marker.  (For some reason, it sill stops at a breakpoint after the clear all, even though dbstatus shows that breakpoint not being present.)

Once bug #46795 has been fixed to allow  dbstop(s)  for a structure  s,  I plan to write a patch to restore all breakpoints after clear all or clear -f.  Does that sound a reasonable approach?  The alternative is to cause the symbols to be removed after clear all or clear -f

Try this code:

clear all;
a = 1;
b = 2;
c = b;

disp(c)

Set a break point wherever and run the script in debug mode.
Everything works fine.

Now comment the line "b = 2;" and run again the code with some breakpoint enabled.

The script fails with an error and the debug mode is halted.
Now it is no longer possible to unset/reset the previous breakpoint. It is necessary to close and open again the script.
